Title 26 › Subtitle A — Income Taxes › CHAPTER 1 — NORMAL TAXES AND SURTAXES › Subchapter P — Capital Gains and Losses › PART V — SPECIAL RULES FOR BONDS AND OTHER DEBT INSTRUMENTS › Subpart A — Original Issue Discount › § 1272
If you own a bond or similar debt that was issued at a discount (original issue discount, or OID), you must count each day’s share of that built-in interest as part of your taxable income while you hold it. You do not have to do this for tax-exempt bonds, United States savings bonds, debt that matures in 1 year or less from issue, or small personal loans between people (not made in business) when the lender’s total loans to that borrower are $10,000 or less and the loan wasn’t mainly to avoid tax. Also, the rule does not apply if you bought the debt at a premium or if you are a life insurance company covered by section 811(b). The daily amount is found by spreading the debt’s increase in value over each day of an “accrual period” (usually a 6‑month period). The increase is based on the adjusted issue price, the yield to maturity (compounded each accrual period), and interest actually paid. Special rules apply if payments can be accelerated (for example, by prepayments in mortgage pools). If you buy the debt after issue and paid extra, your daily OID is reduced by a fraction reflecting that extra cost. “Purchase” means you acquired the debt and your tax basis wasn’t set by the seller’s basis. When you include OID in income, you must add that amount to your tax basis in the debt.
